(FR) APPAREIL D'AFFICHAGE
Abstract
(EN)
A display apparatus is provided. The display apparatus includes a light source, a quantum dot sheet on which a reflective area that reflects light irradiated from the light source and a quantum dot area including a quantum dot that scatters the light irradiated from the light source are alternately disposed, and a display panel that displays an image using light provided from the quantum dot sheet.
